Zebra Stripes Procedurally
A vaguely similar pattern could procedurally be achieved with a Wave texture. Is it physically accurate? No. Is it quick and dirty? Hell yes
Set it to Rings mode and stretch it in one direction using a Texture Mapping node (here in this example the $Z$ axis).
Adjust the Detail to a low-ish value, and the distortion to a high value to your taste.
Lastly run it through a Color Ramp node set to Constant interpolation.
Behold, my potato zebruh with a fake pattern.
